With a 1-inch diameter and a 0.045-inch corner radius, this tool produces controlled edge profiles while reducing stress concentration at part corners. The 4-flute, right-hand spiral geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. At 4 inches overall length with a 1.75-inch length of cut, it fits standard toolholding systems and handles both slotting and profiling passes. Micrograin carbide substrate provides the rigidity and wear resistance needed for production-rate cutting. Licensed machinists and CNC operators install and run this tool in shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use on CNC machining centers and manual knee mills where corner radius profiles are required on ferrous and non-ferrous workpieces. Its centercutting design allows direct plunge entry, making it appropriate for pocketing operations as well as peripheral milling. The bright, uncoated finish makes it a practical choice for applications where coating buildup or adhesion to the workpiece material is a concern, such as certain aluminum alloys or softer steels.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003e0.045-inch corner radius reduces edge chipping and part stress risers\u003c\/li\u003e\n\u003cli\u003e4-flute right-hand spiral with 40-degree helix for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables plunge milling and pocketing\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suited for aluminum and non-ferrous applications\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 1-inch shank diameter for standard toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide corner radius end mill for use in standard 1-inch bore toolholders on CNC machining centers and compatible milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed by a qualified machinist with the machine spindle fully stopped and the control in an E-stop or lockout state per facility LOTO procedures. Use a calibrated torque wrench and appropriate collet or end mill holder to seat the 1-inch shank securely before running. Inspect the cutting edges and corner radius under magnification before each use; carbide tools should not be run if chipping or micro-fractures are visible. Always verify spindle speed and feed rate against material specifications before engaging the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.045 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12182352\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734896247090,"sku":"12182352","price":329.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/be6d4478f4d38d6d2573ef8c1ba3574b.jpg?v=1788767762","url":"https:\/\/voomisupply.com\/products\/accupro-12182352-corner-radius-end-mill-1-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
